Hi,

My customer try Test Mode 1 - Transmit Waveform test in CFG1 bit 15:13.

He found one of four pair send waveform but other don't send waveform. Could you please let me know how to run test mode 1 for all four pair? 

Regards,
Nagata.

    Hi Nagata-san,

    Register 0x0025 can be used to force the test-mode outputs on each channel. It may not be possible to force all test-mode outputs on all channels for each test-mode selected. 

    Reg 0x0025 = 0x0400 //0400: Channel A

    //0420: Channel B
    //0440: Channel C
    //0460: Channel D

    Regards,
    Justin
